its outline, and this plate has a tongue-engaging loop 4 struck therefrom and bent to be out of alinement with the face of the plate memberB. The prongs 5 are formed at the side edges of the plates 3 to bebent to. extend at right angles theretovandfto permit insertion through the body of the envelop, and the spurs 6 are struck from the body portion of the plate on either side of the tongueengaging loop 4, these spurs and prongs being so formed that upon insertion through the body of the envelop and clenched upon the inner side thereof, the plate'member 3 will be secured to the envelop andwill be held against removal from the exterior except that the envelop be mutilated. The flap member 7 of the fastening is also a single sheet of metal 'cnt to, the proper form and then bent into shape; This member 7 has the spurs 8V stamped from the body thereof I and bent to extend to the rear of the plate side thereof to hold the member 7 secured in place thereon. The member 'Z hasa locking extension 9 formed to extend from one edge thereof and located in such relation that when the plate member 7 is secured to the flap of the envelop this extension projects in a relation to be received through the tongue-engaging loop 4 of the plate member 3 secured on the body of the envelop and this locking extension has a spring tongue 10 punched or otherwise formed from the-body portion thereof and bent to project therefrom as is better illustrated in Fig. 4, and thus when the locking extension 9 is inserted through the tongue-engaging loop, 4, this spring tongue 10. will be pressed down to lie in the same plane as the body portion .of

es'jths pri gwtongue ngag s with. a

transverse extent of the tongue engaging loop 4, it is impossible to disengage these parts manually and likewise an instrument 7 as forinstance a knife blade, cannot be inserted beneath the locking extension 9 maistion of abutment against the upturned edge '11 and in consequence a fastening vmeans is p provided'which has the two members thereof so constructed and arranged that When" 7 brought to a closed relation, releasing thereof isprecluded' and the only ay inWhich' access can be obtained to the contents of theenvelop isby mutilatingthe fastening means or by' destroying or mutilating theenvelop and thus furnishing evidence that the con? tents has been tampered With, also it Will.

be'seen that by securing the prongs and spurs 6 of the plate 3 through the overlap-.

ping edges of the seam of the body member 7 1 of the envelop a fastening is provided therefor Which Will prevent access through V this point except by the removal of the mem- 2 5 o r her 3 from its secured position. 7

While I have herein shown and described one specific form of my invention, it will be understood-that slight changes might be nade'in the form and arrangement of'the severalparts of .-the'structure ithout departing fromthe spiritand scope of my infrom the body thereof in a manner to'form a here might be secured to various types of en velopsand 1n varlous connections, andhence I donot Wish to be limited theretoexcept for suchlimitations as the claims may import.
